21.6 ft
Step-by-step explanation:
area of a square 7.5ft
7.5ft ÷ 2 = 3.75
then V = LWH/3
(Lenght, Width and height over 3)
Answer:
Solution given:
radius [r]=3ft
height[h]=5ft
Volume of cone=⅓*πr²h
$ubstitute value
Volume of cone =⅓*3.14*3²*5=47.1ft²
Volume of cone is 47.1ft²
Answer:
Step-by-step explanation:
To solve this system of equations, let's first find the value <em>y</em>. We can replace the x in the second equation with 11 + y, since we are told in the <em>first</em> equation that x is equal to 11 + y. So, let's replace x:
2(11 + y) + y = 19
22 + 2y + y = 19
22 + 3y = 19
3y = -3
y = -1
And look at that - we've found our y-value! Now, we can replace the y in the <em>first</em> equation with -1 to find the value of x.
x = 11 + (-1)
x = 10
So, the solution to this system of equations is (10, -1). Hopefully that's helpful!
